PATENT (irrrcE;

WVISOONSIN, ASSIGNOR OF ONEHALF TO H. C. FORSYTH, OF SAME PLACE.

SPECIFICATION forming part of Letters Patent No. 315,902, dated April1%, 1885.

Application filed October 24, 1884. (No model.)

T at whom, it may concern.-

Be it known that I, THEODORE H. BROWN,

a citizen of the United States, residing at Viroqua, in the county ofVernon and State of "Wisconsin, have invented certain new and usefulImprovements in Plastering, Oalcimining, and Painting Machines, of whichthe following is a specification, reference being bad therein to theaccompanying drawings.

Figure l is a perspective view of this device. Fig. 2 is a detail of thefoot-board. Fig. 3 is a detail of the lower extensible rod; Fig. 4, adetail showing modification of means for raising and lowering thedevice; Fig. 5, a :5 detail of the foot-board bracket.

This invention belongs to that class which is designed to provide meansfor raising or lowering the materials used in plastering, and any likeor analogous work of building or repairing; and the novelty consists ina device in which the load, mortar, or other material to be used can beraised or lowered or adjusted horizontally at will, and in conj unetiontherewith an adjustable stand or support for the workman, also adaptedto be raised or lowered or extended horizontally, all as will now bemore fully set out and explained, reference being bad to theaccompanying drawings, in which like letters designate like parts.

The two posts A A stand, respectively, at each end or side, and arecomposed of two or more pieces, a (1.. These may be made of any desiredmaterial, and in any way or manner, so long as the one part shall moveup and 5 down on or telescope in the other. I have now shown how thismay be done by fixing the lower and stationary part, a, in its base orseat a and providing guides a a to hold and regulate the up and downmovements of the 40 part a. This part can be held at any height by meansof the set screws or clamps b in the guide (1?. The upper portion, a",of this movable part is curved.

The trough or hod O is made of two longi- 5 tudinally-extensible partssecured together in such manner that the trough or hod can be lengthenedor shortened as circumstances require. This trough or hod O is suitablysuspended or held by ropes or chains 0, attached at one end to it 011each side and at their other ends to windlass D, or like means in orupon the base of the part a or there may be but one Windlass, which maybe suitably attached to the top of either fixed part a, and the rope orchain 0, attached at its ends to the hod (J, can be so placed upon andover this windlass that it alone will serve to raise or lower both endsof the trough or hod simultaneously. In this latter instance there willbe placed a pulley in each base a over which the rope or chain may runas it passes to the Windlass. Suitable pulleys, a, are provided at theupper ends of the movable parts a for the ropes or chain to pass over.The hod or trough 0 1S usually of a somewhat Y shape, and of any 6 Idesired size to be fitted and moved between its sustaining-posts.

On the brackets or arms F, which are fixed to the lower ends of themovable piece a, the foot-boardGissupported. Thisfoot-board isso made asto be horizontally extensible. l have now shown in the drawings a way bywhich this can be done, where a series of wooden strips, 9, are fastenedtogether at one end, and mesh with another like series, each series whenso placed in conjunction being fastened together by theenveloping-straps g, which not only serve as a stop, but a securing-bandand a guide. 011 the under side of this foot-board are ways g by whichit can be suitably placed in a fine 3 position on the brackets, I donot, however, mean to limit myself to any particular form ofconstruction, so long as I gain the end of securing an extensiblefoot-board. The bases at are connected together by the rod H, made 8 oftwo pieces, h h, which telescope or otherwise move in or on each other,so as to allow any desired horizontal separation of the posts A A. Theset-screw h affords means of looking these pieces h h upon each otherand hold- 9g ing them fast in any desired position. The base a? is alsoprovided with traveler-rollers I and casters K, so that the device canbe very easily moved when and as desired. The traveler-rollers can belocked in position by means 9 5 I of bolts t, and thus prevent anyaccidental movement of the machine when it is in use. The bases a extendinwardly sufficiently far to act as buffers to prevent the device beingpushed too near the wall or other place where IOO the work is beingdone.

In the fixed part a of the posts or in a there may be anti-frictionrollers a, to render the movements of these parts on each other moreeasy.

In order to adapt the device to use in considerable heights, the posts Amay be made of many extensible pieces, as desired. They can telescope orbe otherwise adjusted upon each other, so long as the extensible idea ispreserved.

Usually it may be desirable to make the device of wood, so as to securethe ends of lightness and cheapness; but the device can be built in veryexcellent shape of metal or of combined wood and metal.

In this device I-have provided an efficient machine or means forenabling the workman who is plastering, calcimining, laying bricks, orengaged in any like or analogous work, to adapt and adjust himself andthe materials with which he is Working to any desired height of room orbuilding. Thus the use of heavy and expensive and cumbersomescaffolding, of ladders, and the hod-carrier can in a very great degree,if not fully, be dispensed with.

The device is very simple in its structure, is not likely to get out oforder easily, and is very excellent for all the uses and purposes forwhich it is designed.

Having thus described my invention, what I consider new, and desire tosecure by Letters Patent, is

1. In a device as described, and in combination' with its base a, therollers and casters, as and for the purposes set forth.

The combination, with a vertically and 5 longitudinally extensible frameor scaffold, as described, of a longitudinally-extensible trough or hod,and means for raising and lowering the same, as specified.

3. A vertically and longitudinally extensi- 4o ble scaffold or framemounted on wheels and provided with a longitudinally extensiblefoot-board, substantially as described.

4. The combination of extensible posts A A with the extensible trough O,and means 5 for raising and lowering the same, the extensible foot-boardG, and brackets F, substantially as described.

5. The combination of extensible posts having curved portions a a, theextended bases 50 for said posts, and a hod or trough suspended fromsaid curved portions, substantially as described. I

6. The combination, in a portable scaffold, of the followinginstrumentalities: vertically- 55 extensible posts mounted on rollers,an extensible foot-board, an extensible tie-rod, H, an extensible hod ortrough, and means for elevating and lowering the same and holding it atany desired height, substantially as described. 60

In testimony whereof I have affixed my signature in presence of twowitnesses.
